Silver nanowires (AgNWs) exhibit strong localized surface plasmon resonance (LSPR), enabling light-field enhancement and interfacial charge transfer. In this study, AgNW/MoS2 composite photocatalysts were fabricated to investigate the effect of MoS2 layer control on visible-light-driven hydrogen evolution. The layer thickness and dispersion of MoS2 were tuned by ultrasonic treatment. With increasing exfoliation of MoS2, hydrogen production was enhanced owing to the synergistic effects of plasmon-induced field enhancement, promoted interfacial charge transfer, and increased active surface area of MoS2. These results provide design guidelines for plasmon-enhanced photocatalysts based on two-dimensional semiconductors.
